2021-01-26iwlwifi: provide gso_type to GSO packetsEric Dumazet
net/core/tso.c got recent support for USO, and this broke iwlfifi because the driver implemented a limited form of GSO. Providing ->gso_type allows for skb_is_gso_tcp() to provide a correct result.

2021-01-22net: octeontx2: Make sure the buffer is 128 byte alignedKevin Hao
The octeontx2 hardware needs the buffer to be 128 byte aligned. But in the current implementation of napi_alloc_frag(), it can't guarantee the return address is 128 byte aligned even the request size is a multiple of 128 bytes, so we have to request an extra 128 bytes and use the PTR_ALIGN() to make sure that the buffer is aligned correctly.

2021-01-20net: dsa: microchip: Adjust reset release timing to match reference reset ↵Marek Vasut
circuit KSZ8794CNX datasheet section 8.0 RESET CIRCUIT describes recommended circuit for interfacing with CPU/FPGA reset consisting of 10k pullup resistor and 10uF capacitor to ground. This circuit takes ~100 ms to rise enough to release the reset. For maximum supply voltage VDDIO=3.3V VIH=2.0V R=10kR C=10uF that is VDDIO - VIH t = R * C * -ln( ------------- ) = 10000*0.00001*-(-0.93)=0.093 s VDDIO so we need ~95 ms for the reset to really de-assert, and then the original 100us for the switch itself to come out of reset. Simply msleep() for 100 ms which fits the constraint with a bit of extra space.

2021-01-20net: dsa: microchip: ksz8795: Fix KSZ8794 port map againMarek Vasut
The KSZ8795 switch has 4 external ports {0,1,2,3} and 1 CPU port {4}, so does the KSZ8765. The KSZ8794 seems to be repackaged KSZ8795 with different ID and port 3 not routed out, however the port 3 registers are present in the silicon, so the KSZ8794 switch has 3 external ports {0,1,2} and 1 CPU port {4}. Currently the driver always uses the last port as CPU port, on KSZ8795/KSZ8765 that is port 4 and that is OK, but on KSZ8794 that is port 3 and that is not OK, as it must also be port 4. This patch adjusts the driver such that it always registers a switch with 5 ports total (4 external ports, 1 CPU port), always sets the CPU port to switch port 4, and then configures the external port mask according to the switch model -- 3 ports for KSZ8794 and 4 for KSZ8795/KSZ8765.

2021-01-20net: mscc: ocelot: Fix multicast to the CPU portAlban Bedel
Multicast entries in the MAC table use the high bits of the MAC address to encode the ports that should get the packets. But this port mask does not work for the CPU port, to receive these packets on the CPU port the MAC_CPU_COPY flag must be set. Because of this IPv6 was effectively not working because neighbor solicitations were never received. This was not apparent before commit 9403c158 (net: mscc: ocelot: support IPv4, IPv6 and plain Ethernet mdb entries) as the IPv6 entries were broken so all incoming IPv6 multicast was then treated as unknown and flooded on all ports. To fix this problem rework the ocelot_mact_learn() to set the MAC_CPU_COPY flag when a multicast entry that target the CPU port is added. For this we have to read back the ports endcoded in the pseudo MAC address by the caller. It is not a very nice design but that avoid changing the callers and should make backporting easier.

mv88e6xxx_port_vlan_join checks whether the VTU already contains an entry for the given vid (via mv88e6xxx_vtu_getnext), and if so, merely changes the relevant .member[] element and loads the updated entry into the VTU. However, at least for the mv88e6250, the on-stack struct mv88e6xxx_vtu_entry vlan never has its .state[] array explicitly initialized, neither in mv88e6xxx_port_vlan_join() nor inside the getnext implementation. So the new entry has random garbage for the STU bits, breaking VLAN filtering. When the VTU entry is initially created, those bits are all zero, and we should make sure to keep them that way when the entry is updated.

In fact, only the PRECHANGEUPPER should have had that check.

(Thanks to Matt Turner for kicking Intel into getting it fixed). dma-buf: - Fix a memory leak in CMAV heap core: - Fix format check for legacy pageflips ttm: - Pass correct address to dma_mapping_error() - Use mutex in pool shrinker i915: - Allow the sysadmin to override security mitigations - Restore clear-residual mitigations for ivb/byt - Limit VFE threads based on GT - GVT: fix vfio edid and full display detection - Fix DSI DSC power refcounting - Fix LPT CPU mode backlight takeover - Disable RPM wakeref assertions during driver shutdown - Fix DSI sequence sleeps amdgpu: - Update repo location in MAINTAINERS - Add some new renoir PCI IDs - Revert CRC UAPI changes - Revert OLED display fix which cases clocking problems for some systems - Misc vangogh fixes - GFX fix for sienna cichlid - DCN1.0 fix for pipe split - Fix incorrect PSP command amdkfd: - Fix possible out of bounds read in vcrat creation nouveau: - irq handling fix - expansion ROM fix - hw init dpcd disable - aux semaphore owner field fix - vram heap sizing fix - notifier at 0 is valid fix" * tag 'drm-fixes-2021-01-15' of git://anongit.freedesktop.org/drm/drm: (37 commits) drm/nouveau/kms/nv50-: fix case where notifier buffer is at offset 0 drm/nouveau/mmu: fix vram heap sizing drm/nouveau/i2c/gm200: increase width of aux semaphore owner fields drm/nouveau/i2c/gk110-: disable hw-initiated dpcd reads drm/nouveau/i2c/gk110: split out from i2c/gk104 drm/nouveau/privring: ack interrupts the same way as RM drm/nouveau/bios: fix issue shadowing expansion ROMs drm/amd/display: Fix to be able to stop crc calculation Revert "drm/amd/display: Expose new CRC window property" Revert "drm/amdgpu/disply: fix documentation warnings in display manager" Revert "drm/amd/display: Fix unused variable warning" drm/amdgpu: set power brake sequence drm/amdgpu: add new device id for Renior drm/amdgpu: add green_sardine device id (v2) drm/amdgpu: fix vram type and bandwidth error for DDR5 and DDR4 drm/amdgpu/gfx10: add updated GOLDEN_TSC_COUNT_UPPER/LOWER register offsets for VGH drm/amdkfd: Fix out-of-bounds read in kdf_create_vcrat_image_cpu() Revert "drm/amd/display: Fixed Intermittent blue screen on OLED panel" drm/amd/display: disable dcn10 pipe split by default drm/amd/display: Add a missing DCN3.01 API mapping ...

2021-01-15drm/nouveau/disp/ga10[24]: initial supportBen Skeggs
UEFI/RM no longer use IED scripts from the VBIOS, though they appear to have been updated for use by the x86 VBIOS code, so we should be able to continue using them for the moment. Unfortunately, we require some hacks to do so, as the BeforeLinkTraining IED script became a pointer to an array of scripts instead, without a revbump of the relevant tables. There's also some changes to SOR clock divider fiddling, which are hopefully correct enough that things work as they should. AFAIK, GA100 shouldn't have display, so it hasn't been added.
